iOS Question [NSConcreteMutableData initWithLength:]: absurd length. Please explain

[tsteward]

So I have started a new app. Use the hosted server.
This app was running fine on my iPhone.
I went and had a coffee then came back and run again but now it keeps crashing, but I didn't change anything.
I tried cleaning the project but same result

Application_Start
Checking and copying DB if needed
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
Error occurred on line: 58 (B4XMainPage)

No I don't but just trying to load xGridListView with a few items

'----Shortcuts----
    xGridLVShortCuts.SetCol(2)
    xGridLVShortCuts.ItemWidth=(xGridLVShortCuts.Width/2)-35dip
    xGridLVShortCuts.AddWithImage("Cars","","",1,xui.LoadBitmap(File.DirAssets,"sc-car.gif"),True)
    xGridLVShortCuts.AddWithImage("Bikes","","",2,xui.LoadBitmap(File.DirAssets,"sc-bike.gif"),True)
    xGridLVShortCuts.AddWithImage("Trucks","","",3,xui.LoadBitmap(File.DirAssets,"sc-truck.gif"),True)
    xGridLVShortCuts.AddWithImage("Tools","Decoding tools","",4,xui.LoadBitmap(File.DirAssets,"sc-lishi.png"),True)
    xGridLVShortCuts.AddWithImage("Codes","Bitting from Key Code","",5,xui.LoadBitmap(File.DirAssets,"sc-codes.png"),True)

My first guess would be to make sure that .ItemWidth isn't being set to a negative value:

'----Shortcuts----
    xGridLVShortCuts.SetCol(2)
    xGridLVShortCuts.ItemWidth=(xGridLVShortCuts.Width/2)-35dip
    xGridLVShortCuts.AddWithImage("Cars","","",1,xui.LoadBitmap(File.DirAssets,"sc-car.gif"),True)
    xGridLVShortCuts.AddWithImage("Bikes","","",2,xui.LoadBitmap(File.DirAssets,"sc-bike.gif"),True)
    xGridLVShortCuts.AddWithImage("Trucks","","",3,xui.LoadBitmap(File.DirAssets,"sc-truck.gif"),True)
    xGridLVShortCuts.AddWithImage("Tools","Decoding tools","",4,xui.LoadBitmap(File.DirAssets,"sc-lishi.png"),True)
    xGridLVShortCuts.AddWithImage("Codes","Bitting from Key Code","",5,xui.LoadBitmap(File.DirAssets,"sc-codes.png"),True)

So I have added even more to this app and it has compiled and run maybe 8 times now without changing any code I get the above error again.

I have cleaned the project. Sometimes this helps sometimes not.

It's making writing a program almost impossible.

It is not related to the compiler.

There is a bug somewhere that causes the BitmapCreator to be initialized with wrong dimensions. It might be a bug in xgridlistview or in your code.
